A Placer County jury was unable to reach a verdict today in the
trial of Christopher Dayton Guerrero, the Sacramento County
sheriff’s sergeant who was prosecuted on charges of driving
under the influence while off duty in 2007.

The jury deliberated for parts of
three days but was deadlocked on the counts of DUI and of DUI with
a blood alcohol level of .08 or higher, leading Superior Court
Judge Joseph O’Flaherty to declare a
mistrial.

O’Flaherty scheduled a court date of June 16 for the Placer
County District Attorney’s Office to decide whether it will
request a new trial.

The Guerrero case stems from a traffic stop on Oct. 4, 2007, in
which a Roseville police officer administered field sobriety tests
and a preliminary
screening test on a breath device that indicated the defendant was
over the limit at which a person is considered legally intoxicated
in California.

Using his discretion, the officer allowed Guerrero to get a ride
home. Further review of the case by Roseville police and the
District Attorney’s Office resulted in the DUI charges being
filed.
